Frequently asked
What's the best mix?
A common framework: pension up to employer match limit (free money first), then ISA for flexibility, then more pension once ISA is filled. Exact balance depends on your tax bracket and retirement timeline.
What about a Lifetime ISA?
Lifetime ISA gives 25% government bonus on contributions up to £4,000/year, but only usable for first home or retirement at 60. It bridges pension and ISA features for under-40s saving for either of those goals.
